Title: metomi/rose#21: custom interface groundwork

This pull request does some of the groundwork for the STASH interface issue - metomi/rose#21.

It implements a couple of things:
* a rename section operation (in menu.py)
* a speed up of the child copy and delete operations for rename
* undo renames as a single operation by introducing a group attribute for stack items.
* do not expand duplicate sections in the config editor page tree, by default

Note: the --new option is an unrelated omission.

@arjclark, please review.
